Sand mastic for sash & case windows in Cranleigh, Surrey
Problem with your window and door surrounds in Cranleigh? We remove the old material, prepare the joints and seal them properly.
- Mastic worn away on windows facing the weather
- Gaps where the frame meets the masonry
- Draughty sash windows at the surround
When to call us in Cranleigh
Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Common reasons people contact us are:
- A silicone bead on a sash window that spoils the look
- Gaps where the frame meets the masonry
- Mastic worn away on windows facing the weather
- Wind and rain getting in round a sash window
If you live in an older home near Church of St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before booking anyone
- Which colour the sealant will be
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
- When the joint can take water or movement
How we handle sand mastic in Cranleigh
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead and we’ll explain which is best for yours. If you have patchy fillers round a sash window and failed mastic on an exposed elevation, we can put it right, whatever the surface.
Houses in smaller places like Cranleigh can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Sand mastic in Cranleigh: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as St Cuthbert Mayne Catholic Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Sashes that rattle, stick or won’t open
- Cracked or broken glass
- Planning or listed building consent (your local planning authority decides)

What the job involves on each surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Why it’s worth doing now in Cranleigh
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Homes in smaller places like Cranleigh can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Common questions in Cranleigh

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is sand mastic in Cranleigh guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
How long does sand mastic take?
That depends on the amount of work, but as a guide it takes a few hours for a single window, longer for several. We’ll tell you when we quote.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
